You probably heard about the Flashback Trojan infecting Macs through a security hole in Java. Apple has now (finally!) addressed the flaw and even shipped a removal tool.

When the whole thing started, I

• Manually checked my machine for infection using instructions posted here. No infection found.
• Downloaded and ran this tool for finding and removing the infection. No infection found.
• Read an article about how the trojan will not infect machines with Xcode installed. I have Xcode installed.
• Installed all but the latest of Apple’s software updates to Java which closed the vulnerability.

Finally installed the very last update from Apple, which includes a removal tool. To my surprise I got this message:

Guess there has been a lot of misinformation about this out there. My advice: run Software Update!
